I share your viewpoint but I think there is a potential solution to this problem (not that I advocate doing it, treat it as a thought experiment): implant the blank slate hardware for the digital copy years before it takes over everyday operation and let it observe your brain to learn. Give the digital copy all the same inputs as the biological brain and make sure the (at first unused) continuous output of the digital copy matches true brain behavior to a desired level of error. Slowly assign control of the biological body to the digital copy over years of time -- somewhere in there "you" may have died but nobody will notice, including yourself. Then when the biological body dies, the digital copy will have already been "you" for quite some time and you're ready to be dropped directly into a mechanical body or a virtual world -- though those would also likely be gradual processes. (I also think the underlying problem of thinking the digital copy isn't you may even be an illusory one in that our consciousness experiences a discontinuity every night when we go to sleep.)
